Features of ATOS Proportional Directional Valves:

1) Enables stepless adjustment of pressure and speed, avoiding the impact phenomenon during directional switching of normally open on/off valves.

2) Enables remote and program control.

3) Compared to intermittent control, the system is simplified, and the number of components is greatly reduced.

4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its response speed is much slower than hydraulic systems, and it is more sensitive to load changes.

5) Low power consumption, low heat generation, and low noise.

6) Will not cause fires and does not pollute the environment. Less affected by temperature changes. The structural principle of the ATOS proportional control valve:

When the input signal increases, the pilot valve 1 of the supply solenoid valve switches, while the exhaust solenoid pilot valve 7 remains in the reset state. The supply pressure then enters the pilot chamber 5 from the SUP port through valve 1. The pilot chamber pressure rises, and this pressure acts on the diaphragm 2, opening the supply valve core 4 connected to diaphragm 2 and closing the exhaust valve core 3, generating output pressure. This output pressure is fed back to the control loop 8 via pressure sensor 6. Here, a rapid comparison and correction is performed with the target value until the output pressure is proportional to the input signal, thus demonstrating that the output pressure changes proportionally to the change in the input signal. Because there is no nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.

ATOS proportional directional valves can control flow in two ways: one is on/off control: either fully open or fully closed, the flow is either maximum or minimum, with no intermediate state, such as ordinary solenoid straight-through valves, solenoid directional valves, and electro-hydraulic directional valves. Another type is continuous control: the valve port can be opened to any degree as needed, thereby controlling the flow rate. These valves can be manually controlled, such as throttle valves, or electrically controlled, such as proportional valves and servo valves. Therefore, the purpose of using proportional valves or servo valves is to achieve flow control through electrical means (of course, pressure control can also be achieved through structural modifications). Since it is flow control, there will inevitably be energy loss. Servo valves differ from other valves in that their energy loss is greater because they require a certain flow rate to maintain the operation of the upstream control circuit.
